The Radiative Transfer Model (RTM) and the retrieval algorithm, incorporated in the SCIATRAN 2.2 software package developed at the Institute of Remote Sensing/Institute of Enviromental Physics of Bremen University (Germany), allows to simulate, among other things, radiance/irradiance spectra in the 2400--24 000 Å range. In this work we present appl...

A preliminary study of the precipitable water vapour (PWV) content above the observatories in Sierra Nevada, the southernmost high altitude location in continental Europe with a dry climate, indicates that Sierra Nevada is a very competitive location for FIR-submm observations, with a 25% quartile of PWV=2.3 mm(H2O) as compared with 2.1 mm(H2O) for...

We present observations of lunar Leonid impact flashes recorded in 2001 November from Spain. Four impact flashes were detected on November 18. Another flash was also recorded on the same night, which appears to be impact related, and two more on that night are possibly, but not unambiguously, of impact nature. On November 19 another flash was detec...

We present the first redundant detection of sporadic impact flashes on the Moon from a systematic survey performed between 2001 and 2004. Our wide-field lunar monitoring allows us to estimate the impact rate of large meteoroids on the Moon as a function of the luminous energy received on Earth. It also shows that some historical well-documented mys...

In November 2004 the lunar phase was adequate to observe lunar impact flashes at the time of the Leonid meteor shower, as it was the case in 1999 and 2001, because a large number of meteoroidal impacts were expected to hit the night part of the Moon visible from Earth. We again arranged a special multisite observing campaign with telescopes aiming...
